(struct callback_data): New structure.
(linear_search): New function.
(callback): Convert to getting auxiliary info passed via a pointer to
a callback_data structure, rather than an unw_dyn_info_t
structure.
Keep track of the maximum load address in max_load_addr.
If an object doesn't have a binary search-table, fall back
on a linear search.
(dwarf_find_proc_info): Fill in callback-data structure before calling
dl_iterate_phdr(). Upon returning, check whether
cb_data.single_fde is set and, if so, return directly, without
searching the DWARF unwind-table.
(dwarf_search_unwind_table): Adjust for renaming of
dwarf_parse_fde() to dwarf_extract_proc_info_from_fde().
If IP doesn't fall into the IP-range of the FDE-entry found
by the search, return UNW_ENOINFO.

Include "tdep.h" on ia64 (we need the cursor).
(bsp_match): Fix it so it compiles again.
(resume_restore_sigmask): Likewise.

(_UPT_access_reg): If the register is out of range, set errno
to EINVAL.
When encountering an error while accessing a register,
print the corresponding error string.

a signal-trampoline, assume that it's a PLT stub.
If non-DWARF stepping fails to change IP and CFA, declare
it a bad frame.
2004/11/23 16:59:56-08:00 mostang.com!davidm
(unw_step): Also print IP as part of the function-trace.
2004/11/23 16:17:37-08:00 mostang.com!davidm
(unw_step): When dwarf_step() fails on a signal-frame, fill in all
the known locations because dwarf_step() fails on older
kernels which don't export the kernel vDSO even though every-
thing else may be providing proper DWARF unwind-info.
2004/10/25 17:43:57+02:00 homeip.net!davidm
Add Debug statement for return-value.
(Logical change 1.290)
2004/11/23 12:49:54-08:00 mostang.com!davidm
(unw_step): If dwarf_step() fails on a signal-frame, fill in the
save-locations for everything that gets saved in the
sigcontext structure.
2004/10/25 17:43:57+02:00 homeip.net!davidm
Add Debug statement for return-value.
(Logical change 1.290)
(parse_cie): Adjust for moving DWARF2 extra-info from
unw_dyn_dwarf_fde_info_t to dwarf_cie_info.
Add support for `S' augmentation ("special frames").
(dwarf_extract_proc_info_from_fde): Rename frm dwarf_parse_fde().
Convert to returning data via dwarf_cie_info rather than
unw_dyn-dwarf_fde_info_t. Allow 0-length FDE since those
can be used to indicate the end of the FDE-table. Return
the end of the FDE via *ADDRP. Ignore CIEs (we may pick them
up during linear searches through the FDE-table).
Fill in the unwind-info only if really needed. When needed,
return the info via a dynamically allocated dwarf_cie_info
structure. Add support for `S' augmentation (ABI/tag pairs).
(Logical change 1.290)
(main): Do some silly FP computations. On x86-64, this ensures
that the signal handler invocations will always be called
with the FPU-state saved as well. Without this, the first
signal was invoked without FPU-state, the second with, causing
a spurious failure.
2004/11/17 02:06:25-08:00 mostang.com!davidm
(get_bsp): New function.
(handler): Clean up & check for error returns.
(main): Also fail if we didn't get SIGUSR2.
(Logical change 1.290)
unwind-info, since DWARF expects us to do so (unlikey for ia64,
where we are guaranteed that the (return) IP points to the
correct unwind-info).
2004/11/17 02:43:39-08:00 mostang.com!davidm
(run_cfi_program): Switch over to using dwarf_cie_info instead of
unw_dyn_dwarf_fde_info_t.
(fetch_proc_info): Clear c->pi before filling it in.
(put_unwind_info): If we got non-dynamic unwind-info, free it
via a call to mempool_free().
(parse_fde): Switch over to using dwarf_cie_info instead of
unw_dyn_dwarf_fde_info_t.
(apply_reg_state): Drop accessees to c->cfa_is_sp.
2004/10/25 17:38:51+02:00 homeip.net!davidm
Fix typo: DW_CFA_CFA_expression -> DW_CFA_expression.

Auto merged

(run_cfi_program): Add missing newline in Debug statement.
(apply_reg_state): It was wrong to do a dwarf_get() on the CFA-location
returned by eval_location_expr(). Instead, we must make sure
we're dealing with a memory-location and, if so, just extract
the memory address as the CFA.
Also, update c->cfa only _after_ the other frame-state has
been updated. This seems to be necessary for correct parsing
of the sigtramp unwind info. Not sure yet this is 100% correct,
but it gets us through Gtest-resume-sig.

(run_cfi_program): Fix typos in Debug statements.

that can be updated atomically (for Linux kernel compat.).
(unwi_full_mask): Rename from unwi_full_sigmask and change type to
intrmask_t.
(intrmask_t): New type.
(define_lock): New macro.
(lock_init): Likewise.
(lock_acquire): Likewise.
(lock_release): Likewise.
(GET_MEMORY): Likewise.
2005/02/20 21:42:54-08:00 mostang.com!davidm
(ALWAYS_INLINE): Include "inline" keyword for compatibility with
Linux kernel.
(ARRAY_SIZE): Rename from NELEMS for improved Linux-kernel
compatibility.
2004/10/25 05:21:51-07:00 hp.com!davidm
(Debug): Make a debug level of N imply that we're printing when
UNW_DEBUG_LEVEL=N since that's more intuitive.

(do_backtrace): Also print backtrace obtained via backtrace().
(foo): Remove backtrace() call---now done in do_backtrace().
